Title: Detecting method for reference point of fingerprint picture
Inventor: KIYOSUE TOMOYUKI
IPC: G06T7/00
Filed: 1983-09-12
Abstract: PURPOSE:To obtain a reference point by performing the artificial Fourier transform a detect the distribution state of picture elements within a small area after separating this small area, and therefore detecting roughtly a cetner point of the entire picture to scan the small area around the detected center point through comparison among areas. CONSTITUTION:A fingerprint is detected by a fingerprint picture extracting mechanism 1, and the picture data supplied to a TV camera part 2 is binary coded by a binary coding part 3 to be temporarily stored to a memory 4. Then the binary coded data is converted through a small area of each part. Then a feature extracting part 6 obtains a power spectrum ¦F(omega)¦, and a CPU5 compares the power spectra to extract a center point of a small area. In this case, an artifical Fourier transform is employed. In case a center point exists, the power spectrum ¦F(omega)¦ corresponding to the frequency omega corresponding to the cycle of a picture which is expanded radially has its peak value. Based on this peak value, the center point of a small area having the maximum power spectrum is decided as the center point of the fingerprint picture.

Abstract: PURPOSE:To improve defocusing detection accuracy and reliability by using a disk whose outer periphery is held as a vibrating means and also using a flexible printed board for leading a signal out of a solid-state image pickup element. CONSTITUTION:A bimorph material 19 to which ring-shaped piezo-electric elements 18a and 18b are adhered on both surfaces of a ring-shaped metallic thin plate 17 is provided at the back of a photographic lens 11, and the outer peripheral part of the thin plate 17 is fixed by a ring-shaped external frame 20 fixed to the lens 11 and an external frame pressure screw 21. Further, an internal frame 22 is fixed to the inner peripheral part of the thin plate 17 by an internal frame pressure screw 23 and the solid-state image pickup element 16 is adhered to the internal frame 22. One terminal of the flexible printed board 25 is connected to the signal terminal 24 of the element 11 and the other terminal is connected to a focusing control circuit 26. The circuit 26 with a BPF compares the vibration phase of the element 16 with a phase wherein a high frequency component varies to detect a front or rear focus state, thereby determining the rotational direction of a focus motor 15. The motor 15 is stopped where the high frequency component becomes maximum and the focusing operation is completed.

Abstract: PURPOSE: To obtain a flowmeter that operates efficiently, positively, and accurately by using a double loop that operates as a sound fork and vibrating the loop at a natural resonance frequency by an electromagnetic driver that operates in synchronization with the vibration of the sound fork. CONSTITUTION: A pipe for causing fluid to be measured to flow is wound around a double loop that is made of circular loops 10 and 11 with a same diameter. Then, flowin edge and flow-out edge metal fittings 13 and 14 are mounted to the edge of a pipe through the openings of side parts 12B and 12C of a frame 12 and the flow-in edge and the flow-out edge are fixed onto the frame 12. Also, a center part (c) that is the connection part of the loops 10 and 11 is fixed to a base part 12A of the frame 12 by a stud 15. In this manner, the loops 10 and 11 at both sides of the center part (c) freely vibrate and constitutes a sound fork that operates as a gear to be twisted. An electromagnetic driver 16 located at the top of the double loop electrically vibrates the loop in inverse phase at a natural frequency of the sound fork.  A twist vibration corresponding to the mass due to the coriolis force of a fluid that flows in the double loop is measured by capacity sensors 18 and 19.

IPC: F16H9/18
Filed: 1984-08-10
Abstract: PURPOSE:To prevent the excessive increase of the friction force between a transmission belt and a variable pulley by forming a pressure receiving surface onto which the hydraulic pressure of a hydraulic cylinder acts onto a movable rotary body of the variable pulley and forming a pressure receiving surface for compensation in the opposite direction. CONSTITUTION:A disc-shaped partitioning plate 84 which contacts in slidable ways with a movable rotary body 76 forms a hydraulic chamber 84 forming an annular space between a fixed rotary body 68. A hydraulic chamber 98 forming an annular space is formed also between the partitioning plate 84 and an installation member 66.

Filed: 1989-06-30
Abstract: PURPOSE:To reduce the effective on-resistance and to set an optimum power efficiency by connecting a constant voltage circuit to a prestage of static induction transistor(TR) connecting to a drive element. CONSTITUTION:It is assumed that a sufficiently small impedance is selected when suspective drive element 21, 22 are turned on. In this case, while the drive element 21 is turned on and the other drive element 22 is turned off, a voltage nearly equal to a negative voltage of a drive source 1 is applied between a gate 31 and a source 32 of a static induction TR SIT 3 and the SIT 3 is turned off. Moreover, while the drive element 21 is turned off and the other drive element 22 is turned on, the SIT 3 is turned on. The gate voltage of the SIT 3 shows a waveform where the voltage level at turn-on is constant depending on the constant voltage characteristic of a diode 4a. Thus, the effective on-characteristic of the SIT 3 is lowered more, small voltage loss is enough and the power efficiency is improved.
